Shrink the hash table of tablebases back to 4096 entries There is no need to make this as large as 65536 just for the sake of the single 7-man tablebase that happens to have the key 0xf9247fff. Idea for the fix by Ronald de Man, who suggested simply to allow more buckets past the end. We also implement Robin Hood hashing for the hash table, which takes the worst -case search for full 7-man tablebases down from 68 to 11 probes (Also takes the average probe length from 2.06 to 2.05). For a table with 8K entries, the corresponding numbers would be worst-case from 9 to 4, with average from 1.30 to 1.29. https://github.com/official-stockfish/Stockfish/pull/1747 No functional change
